Abstract – The electric power system is going through an unprecedented transformation and
related challenges in the implementation of smart grids. The smart grid is based on the
flexible electrical power system that coordinates different energy resources and loads with
the aim of delivering sustainable, economical and reliable electrical supply to the loads in an
efficient manner.
In this presentation, a plug and play type autonomous-microgrid system formation is
proposed. Multiple distributed generating sources and loads interaction is considered
pertaining to the stability of the micro-grid. The proposed method enables communicationless operation of each of the elements of the micro-grid system. It is also considered that the
sources are of different power capacity as can be seen in a typical autonomous micro-grid
system. Spatial Repetitive Controller (SRC) is proposed to control each of the distributed
generating sources in a decentralized manner to stabilize the overall micro-grid system. The
proposed system considers sudden change in load as well as other distributed generators
conditions like a true plug and play operation. A novel signature frequency voltage injection
method is proposed to identify the presence of special distributed generator and operation of
backup distributed generators. The implemented control architecture also ensures stability of
the micro-grid fundamental frequency even in the case of dynamic conditions unlike the
traditional droop-control method. A detailed experimental study is carried out and the
experimental results presented show the efficacy of the proposed system.
